I was shocked to have you raise the question about 'oral lovemaking in the genital area among married couples.' Heaven forbid any such degrading activities which would be abhorrent in the sight of the Lord. For any Latter-day Saint, and particularly those who have been taught in the sacred ordinances of the temple, to engage in any kind of perversions of this sacred God-given gift of procreation, would be sure to bring down the condemnation of the Lord whom we would offend were we to engage in any such practice.

President Kimball (1982):

Married persons should understand that if in their marital relations they are guilty of unnatural, impure, or unholy practices, they should not enter the temple unless and until they repent and discontinue any such practices. Husbands and wives who are aware of these requirements can determine by themselves their standing before the Lord. All of this should be conveyed without having priesthood leaders focus upon intimate matters which are a part of husband and wife relationships. Skillful interviewing and counseling can occur without discussion of clinical details by placing firm responsibility on individual members of the Church to put their lives in order before exercising the privilege of entering a house of the Lord. The First Presidency has interpreted oral sex as constituting an unnatural, impure, or unholy practice. If a person is engaged in a practice which troubles him enough to ask about it, he should discontinue it.
